Question

I interest How to find array in mongoose. for example: if I have this data:

[
   { nums: [2,3,1,4,5] },
   { nums: [2,3] },
   { nums: [1,2,3] },
   { nums: [2,3,1,4,5,10,9] },
   ....
]

and I want only know this array have or not: [1,2,3,4,5]. in this example I get first object: { nums: [2,3,1,4,5] } and size of arrays must match

Use Array.some to check whether the nums property of an item in the array is equal to the array you're looking for:

const arr = [
   { nums: [2,3,1,4,5] },
   { nums: [2,3] },
   { nums: [1,2,3] },
   { nums: [2,3,1,4,5,10,9] },
]

const lookFor = [1,2,3,4,5].sort().toString()
const contains = arr.some(e => e.nums.sort().toString() == lookFor);
console.log(contains);
